Why is Saitama bald?

A hero capable of defeating any opponent with a single punch🥊, Saitama is the perfect example of the character of Shonen who has conquered the hearts of manga fans. Brilliant with his extraordinary physical abilities, he protects the world from invasions of monsters in search of an opponent who will put him in difficulty and thus stimulate his will to always surpass himself.

Among all the characteristics that make One Punch Man's main character so charismatic, there is one that cannot be overlooked: his baldness. 👨‍🦲  Indeed, the hero in the yellow jumpsuit has a 100% smooth skull, which should only increase the interest that fans have in him, making him stand out from other manga characters.

So why is Saitama bald? Is this a genetic characteristic inherited at birth? Does he have a disease that would cause him to lose his hair? These are the questions we will answer in today's article to clarify once and for all one of One Punch Man's greatest mysteries!

Saitama lost his hair due to his workout

Saitama is bald from his training

The reason given in the anime as to why Saitama has lost his hair is simply the intensity of his physical training.

Indeed, the hero with the yellow jumpsuit gained his incredible powers after spending three years training tirelessly on a daily basis. His exercises consisted of a very specific sequence of 100 push-ups, 100 sit-ups, 100 squats, and 10 km (6.2 miles) of running. 🏃🏻 The objective is obviously to increase each day the speed of execution of this bodybuilding work as well as his running speed on the 10 km course.

But why can such training explain hair loss when other manga heroes such as Goku train under more intense conditions in the Time Room without losing any hair? Let's dig into this question together in the rest of this article.

A health problem made Saitama bald

The first hypothesis that comes to mind could be the presence of disease in the punching hero. 💊  In our society, we often associate being hairless with the presence of serious illnesses such as cancer. Know first of all that cancer in itself has no impact on hair loss: it is chemotherapy treatment that disrupts the renewal of hair growth. Moreover, there is nothing to suggest that Saitama could suffer from such an illness in the anime.

Indeed, given the extreme vitality ⚡️ and the extraordinary physical condition of this character, we can on the contrary deduce that he is in Olympian form and that he does not suffer from any health concerns. Also, at no point is it mentioned that Saitama has this kind of problem. His hair loss is therefore not linked to a disease.

Saitama is bald because he has too much testosterone

Testosterone is a hormone secreted by the reproductive systems in humans. It is responsible for muscle development 💪🏻  but it also particularly impacts the development of facial hair. Secreted in large quantities during adolescence, it is the cause of the physical development of young men, the mutation of their voice as well as the growth of their beard, among others. So why would excess testosterone make Saitama bald?

Studies show that males with above-average testosterone secretion tend to go bald in greater proportions than those with normal hormone levels. This can also be observed in professional bodybuilders whose share of bald athletes is much higher than other sports disciplines. This is valid whether they are natural or they use synthetic hormones. 🏋🏻‍♂️

Like these indoor athletes, Saitama practiced muscle-building exercises daily. This training inevitably had an impact on his hormonal secretion of testosterone so that his body could build quality muscles to support his repeated efforts. The question " why is Saitama bald ?" may have a very simple answer: the hero of One Punch Man may have secreted too much testosterone during his 3 years of training, which justifies his hair loss.

Saitama has no more hair due to stress

Another cause that can be directly attributed to his intense sports training is the intense stress felt by the character and his body. Indeed, training the same muscle group every day of the year for 3 years is totally discouraged by sports coaches. To gain strength and endurance, your body needs a period of recovery. This overtraining could have caused physiological stress 🥵 in Saitama, whose body had to draw on its priority energy reserves, ceasing its capillary activity considered useless for its survival.

The second type of stress caused in the white-caped hero is psychological. 😰 Such intense training and a will of steel maintained over time necessarily create a feeling of anguish to overcome. By this, we mean that in order to progress, it is necessary to put oneself in a state of mind where there is a need to face a difficulty. This voluntary emotional stress to become a superman may also have impacted the vitality of his scalp.

Saitama's baldness is voluntary

Finally, the last argument that can justify why is Saitama bald is not based on the actions of the character, his emotions, or his experience, but indeed on a deliberate will of the designer who created this manga. Even if this reason is partly outside the scope of the manga, we think it is important to consider it to analyze this anime as a whole by discovering all the subtleties that it hides.

The first reason that could justify the creation of a bald hero in One Punch Man lies in the humorous potential of this physical trait. 🤡  The explanations given for his baldness during the first episodes of the series, literally give the impression that the hero has lost all of his hair in one night. You'd think he didn't realize it until the early hours of the morning when he discovered himself in the mirror. This amplifies the sympathetic and funny side of Saitama whose personality all the fans adore calm, relaxed even totally jaded and detached from the world.

The second reason that led the mangaka to draw their main character without a single hair on the stone is justified by the incomparable style offered by this appearance to Saitama. 😎  In a world where the most famous Manga characters all have over-developed (San Goku, Vegeta) or very colorful (Naruto, Ichigo) hair, the creation of an entirely bald hero inevitably leaves an imprint in the hearts of fans who can remember their favorite character more easily!

Bald Saitama's style

Moreover, Saitama's appearance is a subtle detail that testifies to a real sensitivity on the part of his designer to make an impression. Until then, no main hero had sported yellow as the main color for their outfit, let alone with a pair of red gloves and boots while wearing a white cape! Adding to that a ball head as Saitama's haircut truly serves as the icing on the cake to come up with a hero who is not only funny, recognizable, and incredibly charismatic.
